Recently switched carriers and with the new SIM my phone and make calls and send texts but it doesn’t receive incoming calls or texts. Data works fine, have tried the SIM in another device with the same problem, so I know it is the SIM and not the phone. I’m wondering if it has to do with the SIM being on 5g, as someone suggested to me? But I don’t understand why I would be able to make calls and send texts just fine.
When data works fine, there is nothing wrong with the phone hardware. All possible errors are from settings or carrier issue.
